Underarms: basically everyday
Legs: depends if my boyfriends back from uni. If he is then basically everyday day (like to keep them smoooooth ), if not then every 2-4 days.
Down there: again depends if my boyfriends home. If he is, then whenever it gets too spikey If not then I keep it trimmed and just do the bikini line like every week or so.

Legs: Only if someone's going to see them, like the girlfriend or if I'm wearing shorts etc. Other than that I'll shave if I notice hairs poking out of my tights at school.
Underarms: Once a week?
Downstairs: Far too much effort. Never.

I really wonder why people bother negging this. Protip: I'll do what I want with my body hair and you can do what you want with yours.
